Armstrong Fluid Technology 116455MF-136A Pump

The Armstrong Fluid Technology 116455MF-136A is a high-performance H54BF Three Phase Circulator Pump engineered for demanding hydronic heating and cooling applications. Operating at 208-230/460Vac with a robust 3/4 HP motor, this industrial centrifugal pump features a cast iron body paired with a non-ferrous impeller to resist corrosion and ensure longevity. Designed for seamless integration with 2-inch flanges, this 1800 RPM unit utilizes a maintenance-free bearing assembly, eliminating the need for manual lubrication. As a part of the renowned Series H In-Line Circulators, the 116455MF-136A provides a direct replacement for 116455-136, allowing for straightforward system upgrades. Its three-piece modular construction and radially-split body design allow for easier servicing without disconnecting system piping. This fixed-speed booster pump is the professional choice for multi-stage zoning and general industrial fluid circulation where reliability is paramount.

• Zero Lubrication Required: Features permanently lubricated, maintenance-free seal and bearing modules to reduce operational downtime.
• Enhanced Durability: The cast iron construction combined with a non-ferrous, non-filtered (NFI) impeller provides superior resistance to system wear.
• Simplified Serviceability: The back pull-out design and radially-split body allow for internal component access without disturbing the pipework.
• Industrial Efficiency: Optimized for high-volume flow in hydronic heating and cooling systems, reaching up to 95 GPM.

• Can this pump be used for potable water systems? No, due to its cast iron construction, this model is intended for closed-loop hydronic heating and industrial cooling; a bronze or stainless steel model should be used for domestic water.
• Is this compatible with my existing 116455-136 installation? Yes, the 116455MF-136A is the modern, maintenance-free direct replacement for the older 116455-136 series.
• What power supply is required? This is a three-phase motor designed to operate on multi-tap voltages including 208V, 230V, or 460V.
